Here's what's changed in the Rift ecosystem recently.
Release 1.6
We've improved the Oculus Store and your Oculus Library in the following ways:
Coming Soon: Check out future apps and games, and get notified when titles you like are ready.
Improved Downloads: You can now choose how much bandwidth to use for Oculus downloads. Also, downloads now resume seamlessly if interrupted.
Automatic Updates: Games and apps installed on your computer from the Oculus Store can now be automatically updated whenever a new version is released.
User Ratings: Rate games and apps, and also see how highly other users have rated an app. User ratings are only available in VR, from Oculus Home.
If you have it installed already, it should update automatically. However, if you are on a really old version and it's not updating, try downloading the setup and choosing repair. Thanks.
